Let ƒ be a function transcendental and meromorphic in the plane and let

where a and the coefficients aj and bj are meromorphic functions of small growth compared to ƒ. Under appropriate conditions on the integers m, k and n, estimates are given for the frequency of zeros of ψ in terms of the growth of ƒ.
